Abstract (en)

[origin: WO2013006902A1] A rotary fluid machine (10) has a rotor (12), a stator (14), and a plurality of gates. The (rotor 12) and stator (14) are rotatable relative to each other and arranged one inside the other to define a working chamber (18) there between. Gates (16) are supported in radial gate slots (20) formed in the rotor (12) and cyclically extend from and retract into the gate (slots 20) as the rotor (12) rotates about stator (14). A plurality of demountable lobes is supported on an outer circumferential surface (24) of stator (14). The surface (24) forms a surface of the working chamber (18). Circumferential surface (24) is composed of an intermediate surface (48) which extends in an axial direction and opposite curved surfaces (46). The gate (16) has opposite rounded corners (130) separated by an axial planar surface (132). The shape and configuration of the gate (16) and corresponding is made to match that of the outer circumferential surface (24) so that when the axial surface (132) lies substantially adjacent and parallel to intermediate surface (48) each of the curved surfaces (130) lie closely adjacent to and substantially parallel with the concavely curved surfaces (46).
